Where do I type in the license code? I'm done and it's wanting to charge me $347- I bought a code for fed and state!

Did you get into the Online version?  That happens a lot.  If you have a License Code you need to install the Desktop Download program and not use the Online version.  How to install with a License Code

If you entered your info into the Online version you can move it to the Desktop program without paying for Online.   To continue in the desktop version see this…….

If you've already purchased the license, open the package and tear off the seal at the top on the right-inside.  Take out the card that says, "Let's get started!"  The location of the web page and instructions to download the product you purchased is all there.  Be sure to begin at InstallTurboTax.com, then select your product.  It should be easy from there.  Hoping this is helpful.
